Answer:

0.654 moles of gas

Explanation:

GIVEN DATA:

Here Volume =10.0 litre=10 dm3

Pressure=203kPa

Temperature:373k

R= gas constant=8.31 L -kPa/ mol-K.

REQUIRED DATA:

n=moles of gas sample

CALCULATION:

FROM GENERAL GAS EQUATION

PV=nRT

n=PV/RT

PUTTING THE VALUE WE GET

n=(203*10)/(8.31*373)

n=0.654 moles
